Designing of antireflection coatings for optical lenses and solar cells

Examples of ARCs designed for ophthalmic lenses and solar cells applications are presented. It have been shown, that for a conventional silicon solar cell a single TiO

thin film allows to reduce the silicon surface reflection to less than 3%. In case of optical lenses, fabricated from a crown glass, few examples of single and multilayer systems with different layers arrangement have been presented and discussed.
